Sudden Loss Of Internet Access?
Jan 10, 2013
For the past year or so I've been using a telstra broadband manager USB to connect to the internet, now all of a sudden I am getting no internet access, not just from the broadband manager but from other networks aswell. I have tried my phones hotspot, other USB's and WiFi's to none of them working.It would start up and work for about 15 seconds, and then internet access would just cut out completely. I have AVG Internet Security 2012 installed and I have tried disabling the firewall (Windows firewall also) and yet it still doesn't work.

Two days ago I lost internet connectivity suddenly on my desktop (Dell XPS 630i, onboard Nvidia network controller, running windows 7 Home Premium 64bit) and have been unable to restore it. As my laptop (winXP sp3) can still connect to the internet and the router settings have not been changed (Dlink DGL4500), I'm making the assuption that my networking problem resides on my desktop alone. the network adapter gives me a 'limited connectivity' symbol and refuses to connect to my network, even though the router acknowledges the desktop's wired connection. The troubleshooting diagnostic sometimes finds nothing, sometimes finds that the computer is not obtaining a proper IP, and sometimes claims the problem is the router. I've also disabled windows firewall. Throughout this whole process I have been getting a 'Drive Power State Failure' BSOD during restarts (about once every four or five restarts, not consistently).
At first I was unable to replace the drivers or uninstall the adapter through device manager. After reinstalling the drivers using the Nforce 650SLI drivers on their website, I was able to do this, but this did not solve the problem. I also did a windows restore to before the problem occured, also with no luck. I've been through the event log and there are numerous code 5007 errors, which just tell me that the adapter timed out during an operation. I've also read through some forums online and tried several solutions including adding a DhcpConnBcastFlagToggle line into the registry: SOLVED: Network Icon Exclamation: No Internet

Until recently I ran windows xp. I shared a built in wall Ethernet jack with another desktop. I used my router (Linksys Befsr41) as a switch by disabling dhcp and connecting the wall ethernet and the two computers to the Lan ports on the router. The other desktop until recently was also running windows xp, but was upgraded and is now an apple imac running os x lion. My internet briefly stopped working but I was able to reset my router and get my internet running again. I then needed to reformat my build and installed windows 7 ultimate 32 bit. I cant quite pinpoint my problem. If I connect straight to the wall ethernet jack i have internet access. However if i use my router as a switch to get internet for both my pc and the apple imac, I will not have internet access. Sometimes the internet does indeed come back on in this circumstance, only to get disconnected again shortly. I am not sure who to blame because the router worked fine when spliiting ethernet for xp machines, and I have internet access when running straight from the wall to my pc

Everything on my computer was fine this morning when I left for week, but upon my return I noticed that my keyboard/mouse wasn't working. I restarted my computer and confirmed that my keyboard works in the bios and whatnot, but when I get to the windows login screen, I get no response from the keyboard or mouse.the mouse is a simple USB one, and I'm using a PS/2 keyboard, so I doubt it's some sort of sudden driver issue.I tried logging into safemode, and I get the same result, can't move my mouse or use my keyboard.Does anyone have any idea how to possibly fix this issue? I'm unable to restore from an earlier state either.

Verizon Fios, Actiontec Router. Windows XP machines (wired) (2) never any internet loss whatsoever. Running the wireless from the Actiontec and also a Linksys that is on one of the ports. (distance issues) The Linksys always syncs up and both wireless systems work 100% all the time with either XP or Win 7 laptops.
Here's the issue: two wired desktops running Win 7 have intermittent internet drops. One is older, one brand new fresh out of the box. Turned off the power saver NIC card function on both, WOL disabled. That's not the problem because the internet losses occur sometimes after the machine is on for a few minutes, the PC does not sit long enough to go into power saver anyway. There's no rhyme or reason as they say when the loss will occur. Sometimes this will not happen for a day or more, other times it can happen after using the machine for just a few minutes.One thing I have been trying is to disable IPV6 then I can get the internet back, othertimes re-enable it to get the net back. Go figure. Again, disabling it will not fix the problem, however switching it on/off will. Disabling and re-enabling the NIC will only fix it sometimes, most instances that does nothing. There are different types of NIC cards in the machines, one uses a Realtec on board, the other uses Nvidea on board and a plug in NIC (brand?) all NIC cards/board performs the same.Also, when they DO work, if I let them boot for a while, usually they will be fine, but that's looking at a 10-15 minute boot up. (doesn't take an excessive time for actual boot-up but I mean just leave it alone for 10-15 min) The Actiontec has the most current update version, and is about two years old. Somehow these machines lose the internet portion but not the network portion. Such an annoying problem, even more so when I added a brand new machine and get the same issues. I would be willing to bet that if I ran them wireless there would be no issue, but that's going to slow down the dl/ul speeds that I get with a wired connection.

My computer is relatively recent only being bought back around Feb/March. For the past month the machine has been crashing and when I log back in I need to restart my router in order to get my internet connection back. The strange thing is that other computers connected to the same router also lose their connection shortly after the BSOD on my machine (both machines have wired connections). I am using the same OEM copy of Win 7 Professional 64 bit that was installed when I bought the machine.I have tried updating the drivers on the network card but that does not seem to help. I also tried looked at the dumps with WinDbg to see if I could find a specific driver that was playing up. I also turned on the driver verification a couple of times to see if I could find a driver that was suspect -- that caused almost immediate crashes but I could not get to the bottom of what was causing it but it could make it happen by starting up Mumble.The BSODs have so far seemed to happen when I am playing a game, using something like Mumble, or watching a stream.

This morning (Wednesday) my desktop computer brought in automaticly Tuesdays (26/04/11) set of patches, 6 in total for my machine. I turned the computer of for as I headed of to work and they installed on the shutdown. On returning from work the updates continued the install procedure on loading, but stuck at 0% for over 20mins. I decided to check the install time for this stage on my laptop 7pro x86 and it wizzed through in a few moments (laptop is a good 6yrs old). I figured the desktop was stuck and hit reset, every time it would get stuck at 0% on configuring the updates. Booted into safemode and ran system restore to the morning. Computer now loads up ok but will not connect to the internet. It would appear that its not getting an IP from the router.
What i've tried so far:After running system restore I've removed the Anti virus (Eset Smart Security). Tried setting manual ip address and ping router and laptop, also tried ping from laptop to desktop, both ways destination unreachable. reinstalled network drivers, same fault occurs. Reset winsock (netsh winsock reset catalog), rebooted after. reset TCP/IP (netsh int ip reset c:esetlog.txt), reported ok, rebooted same fault. ran sfc /scannow, reports system file integrity ok.Unchecked IPv6, same issue occurs. Checked network cables on laptop, ok.

I have a desktop with wireless access thourgh a USB wireless card (SMCWUSB-G)
I don't know what else to do. I have tried everything. I have searched around in forums, asked people. I need an internet expert.
I have a 20Mb internet plan but after swtiching from Windows 7 32-bit to Windows 7 64-bit i dont get more than 2Mb, normally only 1Mb. Plus now my signal is weaker, i'm only getting 2 bars out of five when i used to get 3 or 4.
My download speeds don't get passed 30kb/s and i lose connection all the time now. I can say its not the distance from the router. Here is what i have tried to solve it:
- DOS command: "netsh int tcp set global autotuninglevel=disabled"
- TCPOptizmier: gotten only worse and i think it was when my signal started to get weaker.
- Disaled IPv6 in internet options
- Disabled QoS

I am having a nightmare with my windows 7 64 bit home edition. It is running extremely slowly. I have lost the internet connection and the windows firewall has turned off and cannot be turned back on. Whenever I boot up i get the message "failed to connect to a windows server" The event viewer log is also unavailable. I have established that my internet is working on other machines. I have also attempted to reset winsock in safe mood. However this has not worked.I've had the system for about 9 months with no major problems. I have McAfee and have run windows defender and adaware so I am pretty sure it's not malware.

[code] I never had this issue on Windows Vista, occasionally my internet will randomly dropout. Limited Internet Access". When it does I can do a few things to get it working again:
- Disable, then enable my wireless card and reconnect.
- Uninstall the card, then re-install and reconnect.
- Disconnect from the internet myself and reconnect.
Either way it gets super frustrating. There is 1 other computer plugged directly into the router that does not experience any issues. In addition, I have 1 laptop (windows 7) that works great and 1 laptop (Windows XP) which works great.

I had a power loss while running on battery (it still showed power left, but suddenly shut down anyway) and when I restart, it reports that the Windows is not activated and Window is not genuine and system might be a victim of "counterfeiting."
Is this a virus (I have MSE on continuously and about once a week scan with Malwarebytes)? I have run 'sfc /scannow' with filtered output ('findstr /c: "[SR]" c:.....logsCBSCBS.log" and it appears as usual.
How can I lose my Windows activation?

When my computer says Internet Access, I am having trouble browsing.Most pages do not load.Right now, It says no internet access for over 15 minutes and I am able to brose so much better and still going on downloading around 400 kb/s.(I am on a wired connection from a cable internet with NetGear CGD24G Cable Modem (I don't think it is a wireless router). There is wireless connection on the modem, but I am on a wired connection, and I am posting this while it still says no internet access).

i recieved my new lenovo z570 ideapad yesterday...i'll just put some of the spec down incase you want to know.
proccessor: intel i5 (second gen)
graphics: nvidia geforce
os: windows 7 64bit
yadayadayada...
anyway, after charging it up and turning it on, i started to install programmes and other bits and bobs. e.g ituens, flash player. just the usual essentials. i used the laptop to watch videos on Internet, genenral browing such as facebook, so in short, the internet was working fine. just before i went to bed that night i installed avg security (free version) and ran a full scan. when the scan finished, i put the laptop into hibernate, and went to sleep! happy in the knowledge my new gizmo was running smoothly!
just before i woke up i heard the laptop turn off as it had run out of charge. so i plugged it in and charged it up, then turned it on. this is where the problem starts...i connected via wifi however the logo at the bottom right of the screen showed the signal strength meter on empty, with a yellow star covering it. i clicked the icon, and it said, 'not connected, connections are available' and below shows im connected with 5/5 signal strength, but on 'limited access'.
1) there might be a problem with the driver for the local area connection adapter
2)there might be a problem with the driver for the wireless network connection adapter
there are 28 updates, but im unable to update them as i have no internet connection. i also cant connect via the ethernet cable.i cant roll back the drivers as there are no previously installed ones, and i cant update them as i am already up to date.my other laptop (acer aspire 5630 running on vista) works perfectly fine using wifi and the ethernet cable, so i honestly dont know whats wrong. after reading things on my acer about ways to fix the problem i came to the decision to restore the laptop to the time of my first installation which was adobe flash player (which i installed the day before.) i was unable to do a full factory reset as the only options available are to either restore to a backup, or re-install windows (which requires a disc, which i dont have). i also didnt configure a backup as i had only had the laptop a day!

I have a Dell Inspiron N5110, Intel core 3 processor, and Windows 7 ultimate 64 bit os. I have recently reinstalled windows 7 from the windows 8 os. I can't access my wireless internet, I can only get to the internet via hard wire. I have searched Dell and Intel for the network controller driver and the sm bus controller driver, but to no avail.

This is a problem that has probably been solved but I have spent some time looking for the solution without success.
Windows 7 (6.1.7100 build 7100) indicates that I have no Internet connection in spite of the fact that I can browse without any problems (see attached image).
Mostly this is not a problem except that I want to connect to an external server to upload files. Normally I use map network drive for this. When I attempt this, I fail because it doesn't see the Internet connection.
I have tried the following solutions which haven't worked
Disabling link scanning in AVG Disabling all other network connections

I was installing a software on my other laptop (it had SQL software with it) and I ran into some trouble as I got error problems that the installation of the software had failed and now whatever I do, I can't access the web! Sure enough, my wireless connection connects successfully and it indicates that I am on the "Internet" but every time I try to use either firefox or internet explorer to go to a web site, it says I don't have a connection.

I am running a modem and wireless router which is working fine. I have my home computer up and running (Windows 7)- no problems at all. However, my work laptop (windows 7 professional) will connect to my wireless network but will not 'access' the internet. I have set up a connection from scratch; changed the network settings; restarted (everything) plugged in wth Ethernet cord; run a router check... and honestly I am way out of my league in figuring this one out.I tried several of the solutions for forum threads around the problem of 'connected to internet but no internet access', but part of my confusion is that one computer works fine, but the other simply won't allow access. When I use a when I use an open network it won't allow me on at all. But when I set up my private network it will connect and show internet access for 10 SECONDS at a time and then No access... like a constant flicker...

I have just come back off holiday to find that my 2 week old Acer aspire running windows 7 home premium will not connect to the internet, but my girlfriends laptop connects just fine, this is very frustrating. I am not running any adobe software or running antivirus / firewall software at the moment. I can connect to the router, I just don't have internet access what so ever!Whilst on holiday I managed to pickup a BTOpenzone network, but due to ridiculous browsing prices, I just left it. Before anyone asks, yes I have tried disabling and enabling, releasing and renewing etc, I don't understand how I can fix this problem! I have tried everything I can think of!I ran ipconfig /all and this was the result[CODE]

For some weird reason I can only access the internet through IE8.I'm on a wired ethernet directly to the modem and up until a week ago everything worked fine. I then had the bright idea of installing a wired router so two computers could access the internet at the same time.Obviously I did something wrong because the while the original computer now continues to access the internet through the modem just fine (I removed the router), after reconnecting my computer to the modem and resetting the modem all I can use is IE8.

A couple days ago, I grudgingly allowed someone to install Norton on my desktop computer. It's running Windows 7, fyi. Immediatly after it was installed, I was unable to connect to the internet. It can find my router, and it tells me I'm connected, but with limited access, and all it says is identifying. So I can't get onto the internet. I tried the troubleshooter built into Windows 7, and it told me there isn't a problem. I tried to system restore back to before I installed Norton, and I tried two or three times, and it failed everytime. I tried to return my windows firewall to its recommened settings, and it said it can't change some of my settings. My computer is the only device having the problem, which led me to believe it was Norton's fault. So I uninstalled Norton, and it didn't fix the problem. I tried to use a network cable to share the internet connnection from my laptop (which works fine), and it had the same problem as when I tried wirelessly.
I tried reseting my TCP/IP stack, and that didn't work. I'm not sure what I should do. I'd be grateful for any insights you might have =DNorton also found 6 high level trojans, apparently, which it promptly got rid of, so the problem could be that it messed up one of my system 32 files, but I don't have a windows disk lying around to repair with, so I was hoping to try some other fixes before I go out and buy a new disk
